Thanks! Sorting out visas etc is definitely a concern for the US, but that's a good point about encryption. It's hard to imagine Google and Facebook sitting quiet while bad stuff happened in that area.
Google and Facebook haven't had much effect on the "bad stuff" from the last six months. I wouldn't be confident about their ability to influence encryption legislation, since they haven't been able to change the administration's mind on immigration, climate change or net neutrality so far.
